From: A case study of a collision tumor composed of cancers of the bile duct and pancreas
The resected specimen demonstrated tumors in both the bile duct and the pancreatic head. Stenosis due to bile duct invasion by pancreatic head cancer was noted in both the pancreatic and the bile ducts (black arrow). Stenosis was also noted in the middle bile duct, suggesting bile duct cancer (white arrow). The yellow arrows were the stump of the bile duct.
